SUCKER ROD PUMP TECHNOLOGY OF SLANT HOLE IN VISCOUS OIL RESERVOIR

This paper introduces the application of sucker rod pump in first group of slant holes in viscous oil reservoir in China. The beam pumping units can satisfy the need of stream injection and oil production without trip downhole tubing string. It also introduces the performance and feature of special tools used for sucker rod pump in slant hole, analyses and calculates the spacing of centralizers in slant hole and polished rod load of slant hole pumping unit. It summarizes the features of sucker rod pump technique in slant hole.
